“Embrace the change”
—Lady Gisela, in Legacy
Keefe's Legacy is a legacy Lady Gisela has mentioned several times to Keefe. A lot of it remains mysterious. Lady Gisela's Nightfall may have something to do with it; Lady Gisela has said before that she has planned out a solution to the elvin world's problems and that, like it or not, her son was part of those plans. It also may have something to do with Keefe’s mysterious ability, which has, as of Legacy, not been revealed. There is also the theory that Keefe's ability will be the ability to block other abilities or take away abilities because the last time Shadowflux and the full spectrum were mixed, Ruy was unable to make force fields.
